Weathering the winter with energy efficiency

Solar Panels at UFS Qwaqwa Campus — Revolutionising electricity with sun power: Solar panels at the Qwaqwa Campus.

Over the past few years the University of the Free State (UFS) has been planting panels, now the time has come to reap. Solar farms produced a return on investment in the form of R1.4 million in savings as a result of photovoltaics (PV) between January and March 2019. Nicolaas Esterhuysen, an electrical engineer at the Department of University Estates also reported a 2.34% decline in electricity usage between 2013 and 2018.

Solar panels are the future

According to Esterhuysen, the solution to a power crisis lies in “either becoming more energy efficient or generating our own at a cheaper cost”. All campuses have managed to save a total of R5.4 million in 2018 through producing our own power (solar PV) and actively managing the instantaneous load demand with building management system (BMS) software.

Overall, ground-mounted PV installations at all campuses contribute 2609 kilowattpeak (kWp) under standard conditions. The Bloemfontein Campus accounts for 979kWp of that amount while the South Campus generates 762kWp, with the Qwaqwa Campus producing 748kWp, and the Paradys experimental farm bringing in 120kWp to the grand total (to be commissioned June 2019).

Rooftop PVs generate electricity through the 80kWp Muller Potgieter Building, the 255kWp Bloemfontein Campus computer lab, the 35kWp Qwaqwa Campus computer lab, 135kWp Qwaqwa Campus Mandela Hall, and 416kWp Thakaneng Bridge panels. This is a total of 921kWp.

Winter is coming with tariff terrors

A 15.63% electricity tariff increase is projected this year in light of the annual winter adjustments commissioned by Eskom and Centlec. To gear up for the associated spike in power use over this season, University Estates advises the Kovsie community to use energy efficiently. “Think twice before switching on the heating and make sure to switch it off when you leave the office,” advises Esterhuysen.

In addition to generating electricity, saving initiatives such as implementing light-emitting diode (LED) lighting with motion sensors and actively managing demand at peak times have been implemented.

What’s next?

The next step is to rethink dated mechanical installations that are used to heat some of our older buildings. Replacing similar installations across all of the campuses are some of the ways the university intends to escalate energy efficient in future.

Faculty of Education discusses new curricula at summit

2012-03-07

Die Fakulteit Opvoedkunde se nuut-aangepaste B.Ed.-programme word binnekort by die Nasionale Departement van Hoër Onderwys en Opleiding ingedien vir herakkreditasie. Proff. Rita Niemann (links), Direkteur vir Nagraadse Studie en Navorsing, en Gawie du Toit, Direkteur vir Aanvanklike Onderwysersopvoeding, is aan die stuur van die herkurrikuleringsproses vir voorgraadse en nagraadse programme van die Fakulteit Opvoedkunde.

The training of professional teachers rests on a strong curriculum. For this reason, the Faculty of Education has been re-looking at the curricula of the B.Ed. programme for the past two years.

Before this programme is submitted for approval and accreditation, the Education Faculty’s staff from the Bloemfontein and Qwaqwa Campuses will attend a summit at the Gariep Dam on 7 and 8 March 2012. This summit is a sequel to guidelines drawn up by the National Department of Higher Education and Training on adjusted requirements for teacher training. It determines that all initial teacher training and honours programmes be recurriculated and resubmitted for accreditation. These requirements were published in the Government Gazette in July 2011 and involve all education faculties in the country.

Deans and line heads of other faculties, including Natural and Agricultural Sciences, Humanities, and Economic and Management Sciences, have also become involved as Education students often register for modules in these faculties.

Last week a team from the UFS’s Education Faculty also attended a workshop presented by the Council on Higher Education where the criteria for recurriculation and the evaluation of programmes were discussed.

Prof. Gawie du Toit of the UFS’s Faculty of Education says curriculation is not merely a technical process but requires thorough reflection and conceptualisation, involving various roleplayers.

“It is important that recurriculation should take place over a period of time to allow for sufficient time for reflection, absorption and ownership.”

Thus, the aim of the Gariep Dam summit is to introduce a teachers’ training program that will provide graduates with the necessary knowledge, skills and responsibilities to take up their places as academics and professional beginner teachers.

During these two days students in Education will not attend any classes but they are tasked with self study and to complete assignments.
